PATENT "OFFICE.

STARCHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 400,184, dated March26, 1889. Application filed February 14; 1888. Serial No. 263,961. (Nomodel.)

To all whom, it may concern:

Be it known that I, THOMAS J. BLAKE, a citizen of the United States,residing at Vilkinsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inStarching- Machines; and I do hereby declare the following to be a full,clear, and .exact description of the invention, reference being had tothe accompanying drawings, which form part of this specification Thisinvention has relation to starchingmachines, and especially to thatclass ofnnachines particularly designed and adapted for starching shirtsand other large articles of underwear.

The object of my invention is to provide means whereby the starch willbe forced into and through every part of the fabric, while ample andefficient provision is made for the escape of the air from the folds andcavities while the articles are being pressed.

My invention has for its further object the provision of novel means forautomatically removing the surplus starch from each article after it hasbeen thoroughly saturated or impregnated.

My invention consists in the novel con struction, combination, andarrangement of parts, as hereinafter described, and specificallyclaimed.

In the accompanying drawings, Figure 1 is an end view, and Fig. 2 a sideelevation, of my improved starching machine; and Fig. 3, a detail viewof the mat.

A designates a rectangular frame upon which are supported the workingparts of the machine.

B B are standards or brackets, supporting above the frame A theperforated cylinder 0 and the pivotal arms D D, which carry thewiping-roller C E designates the starching-table, which consists of ashallow oblong metallic box having a horizontal surface and adaptedtocontain hot water, which is supplied thereto from a boiler by means'of a hose, e. This table is mounted 011 a platform, F, to which 'arejournaled rollers or wheels ff, arranged to travel on suitable ways orin grooves or channels formed in the track-bars g g, laid upon andrunning lengthwise of the main frame A.

A horizontal toothed rack, O, is attached to the under side of theplatform F, and the latter receives reciprocating motion in thedirection of its length from a transverse shaft, H, mounted on the frameA by means of a toothed segment, I-I, fitted to said shaft and engagingwith the teeth of the rack C.

To the upper surface of the table E is secured a web or mat, 1,consisting of a sheet of rubber having its surface indented so as toform a large number of cavities to receive and hold the starch, which isfed thereto in any convenient manner.

The roll 0 is a large hollow metallic cylinder, preferably of brass orcopper, and is mounted on a shaft, 0, having its ends supported in theside pieces or brackets B B. The cylinder C rotates upon its shaft whilethe ends of the latter rest upon springs 19 b, and are pressed down bymeans of rubber blocks, d, to which are attached adj Listing-screws d(1, turning in bearings in the tops of the brackets B B, and providedwith hand-wheels d on their upper ends. The walls of the cylinder 0 areperforated with holes, the purpose of which is to allow the air toescape frpm the fabric when the starching-table is passing under thecylinder and into the cylinder. When a solid or im perforated cylinderis used,

no escape for the air is provided, and its ac cumulation and retentioninside the folds of the fabric greatly interferes with the entrance ofthe starch and thorough impregnation and saturation of the articles. Thestarch on the surface, instead of being driven into and through thefabric, is forced back by the roll onto the table or off on the sides orends. The cylinder 0 is so situated that its surface and the surface ofthe mat I upon the table are in close-pressure contact when the latteris passing under the cylinder. The pressure, however, is not rigid, butis made yielding by the rubber blocks 61, which allow the cylinder toadapt itself to the varying thickness of the goods.

The wiping-roll 0 consists of a cylinder, of wood or other material,having a cloth cover in several folds or layers, and is intended andadapted to be swung down upon the starching-table in contact with thegoods at intervalsthat is after the table has passed a sufficient numberof times under the pertorated roll and the goods have taken up enoughstarch, the wiping-roll takes up the surplus starch from the goods andleaves them 111 condition for the next operation.

In the machine under consideration the wiping-roll is brought into playafter every fourth movement of the starching-table, and its action isgoverned by the mechanism to be described. I 'lhc arms I) D, by whichthe wiping-roll 1s carried, are attz'lchetl to a transverse shaft, M,journaled in the arms 7; is, projecting from the edges of the brackets II3.

toothed lever, 7: pivoted to the side of one of the brackets .1) I Atits lowerend thclever 1.1 is coupled by means of a lateral pin or pivot,lrflpassing through a slot, 7:, in a swinglng bar, I, which is pivotedat I to one of the sides of the frame A, the several parts being soarrai'lged that any motion imparted to the bar I will be transmitted tothe arms I) 1). Normally the arms l) l) are in an upright position, asshown in black lines in Fig. '1, the wiping-roll being nearly directlyabm'e the perforated cylinder. The shaft M, supporting arms I) I), isjournaled about ou a. line with the slntft of the roll U, and the armsI) I) are bent ate to allow the wiping-roll to reach the table. In theposition shown the arms aremaintained until. otherwise required by thetension of a spring, N, upon the bar Z, which also serves to return thewiping-roll to the position shown after it has done its work.

The movement of the \vipin -roll is effected through the medium of anottset or cam, m on the faceof a toothed wheel, in, journaled to theframe A. A transverse main powershaft, N, carries a pinion, N, whichengages with the wheel in, and is proportioned as to make fourrevolutions to one of the wheel n1". Upon one end of the shaft N is acrankwheel, 0, which is connected by a pitman, O, with a crank-wlmel, 0on the end of the shaft II, so that the revolution of the wheel willproduce an oscillation or reciprocation of the wheel 0" and rectilinearor horizontal reciprocation of the starchingtable through the medium ofthe segment II and rack 0".

At every fourth revolution of the shaft and every single revolution ofthe wheel m the offset or cam m comes in contact with and swings ormoves the bar I to one side, thus causing the wiping-roll. to fall uponor iii the way of the starching-table, where it remains during thebackward movement of the table from beneath the cylinder 0 and gathersup the starch remaining unused upon the surface of the goods. After thecam m has passed the bar I, the latter is thrown back into position andthe wiping-roll is raised.

The wiping-roll and shaft are detachable,

l The arm I) is formed or provided at its lower end with a T toothedsegment, 7. which engages with a 1 so that when the former hasatwinnulated a large amount of starch it can be taken out and soaked inwarm water to wash. out the starch, a new roll being meanwhilesubstituted. For the purpose of allowing the wiping-roll, with itsshaft, to be detached the arms D D are notched, as shown at D to receivethe ends of the shaft, which is held in place by removable pins I).

The main shaft N is provided with suitable clutch mechanism, I, wherebyitmay be thrown into and out of gear with the toothed wheel. T in meshwith pinion 1 on main pullcy-shaft s.

5 S are fast and loose pulleys, which carry a shifting-belt, Q,by whichthe machine may be started and stopped at pleasure.

The clutch I is employed in stopping and starti ng the machine betweenstz'u'ching operations.

Ilaving described my invention, what I claim, and desire to secure byLetters latcut, is I I. In astarching-machino, the combination, with thecarrier upon which the articles to be starehed are laid, of apressure-roll consisting of a hollow perforated metallic cylinder,substantially as and for the purpose set forth.

2. In a starchhug-machinc, a detachable wiping-roll consisting of acylinder mounted on adjustable arms and ca ntblc of being lowered uponand raised from the starching table or carrier, substantially asdescribed.

In a starehi ng-nntchine, the combination, with the reciprocating starching-table, of the pivotal arms I) l), toothed segment 7.2 upon one ofsaid arms, the toothed lever 7." mounted on the frame of the machine,lever 7, pivotally connected to lever lr wheel N, having offset 171%,pinion N, and transverse shaft 'N, substantially as described.

4:. In a starching-machinc, thecombination of the following elements, towit: the \vi iingroll, the toothed lever su]j)porting the same, thetoothed segmental lever, the swinging bar, the toothed wheel. having acam or offset on its face, and the pinion engaging with said wheel andmounted on the shaft, substantially as described.

5. In a starching-maclline, the combination, with the reciprocating starching-table, the pressure-roll, and the wi pin g-roll, of thetransverse shafts through which motion. .is convcyed to the table and tothe arms supporting the wiping-roll, the crank-wheels on said shafts,and the connecting-pitman, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this28th day of January, 1888.
